1,2,4-Triazole Conjugates as HEGFR Inhibitors: Synthesis, Anticancer Evaluation, and in Silico Studies
(Wiley-V C H Verlag GmbH, 2026) Bulbul, Bahadir; Kulabas, Necla; Gurboga, Merve; Ozakpinar, Ozlem Bingol; Cakmak, Ummuhan; Tuncay, Fulya Oz; Kucukguzel, Ilkay
A series of novel 1,2,4-triazole-acetamide derivatives was synthesized and evaluated for anticancer and hEGFR inhibitory activity. The compounds were obtained via multistep synthesis and characterized by spectroscopic methods. Cytotoxicity was tested against PC-3, MCF-7, A549, and K562 cell lines. Compounds 18, 19, and especially 24 showed notable antiproliferative effects, with compound 24 exhibiting higher selectivity and potency than gefitinib. It also induced apoptosis and inhibited migration in A549 and PC-3 cells, while selectively promoting invasion in PC-3, suggesting EMT-related behavior. In vitro kinase assays revealed compound 20 as the most potent hEGFR inhibitor (IC50 = 43.8 +/- 1.3 nM). Molecular docking and 200 ns molecular dynamics simulations confirmed its stable interaction with EGFR, particularly involving Cys797. These findings highlight compounds 20 and 24 as promising candidates for further development as EGFR-targeted anticancer agents.
Ameliorative Effects of Myrtus Communis L. Extract Involving the Inhibition of Oxidative Stress on High Fat Diet-Induced Testis Damage in Rats
(Taylor & Francis Ltd, 2024) Coskunlu, Busra; Koroglu, M. Kutay; Hersek, Irem; Ertas, Busra; Sen, Ali; Sener, Goksel; Ercan, Feriha
The possible protective effects of Myrtus communis L. (MC) extract on a high fat diet (HFD)-induced testicular injury in a rat model were investigated using histological and biochemical methods. Wistar albino rats were divided into three groups: a standard diet control group; a HFD group; and an HFD+MC group. The HFD and HFD+MC groups were fed with a HFD for 16 weeks. MC extract (100 mg/kg) was given orally five days a week to the rats in the HFD+MC group during the last four weeks of the experiment. Leptin, triglyceride, high-density lipoproteins, cholesterol, estrogen, testosterone, LH and FSH were analyzed in blood serum. Sperm parameters were evaluated from the epididymis. Testicular morphology, proliferative, apoptotic and NADPH oxidase-2 (NOX2)-positive cells were evaluated histologically. Testicular oxidative stress parameters were analyzed biochemically. In the HFD group, lipid and hormone profiles were changed, abnormal spermatozoa, degenerated seminiferous tubules with apoptotic and NOX2-positive cells were increased in number, and sperm motility and germinal proliferative cells decreased compared to the control group. Moreover, testicular malondialdehyde, 8-hydroxy-2-deoxyguanosine and myeloperoxidase levels increased, whereas glutathione and superoxide dismutase levels decreased in the HFD group compared to the control group. All these histological and biochemical features were ameliorated by MC treatment of HFD-fed rats. In conclusion, HFD caused alterations in sperm parameters and testicular morphology by increasing oxidative damage and apoptosis. MC extract may have potential protective effects by inhibiting oxidative damage.
Assessment of the Nutritional Status of Syrian Refugee Women in the Lactation Period
(Sage Publications Inc, 2026) Isik, Tulay; Garipagaoglu, Muazzez
Background: The Syrian civil war has caused large-scale displacement, with many Syrian refugee women migrating to T & uuml;rkiye. Lactation is a critical period requiring adequate nutrition for maternal and infant health. However, data on the nutritional status of lactating Syrian refugee women are limited. Aim: This study aimed to assess the nutritional status of lactating Syrian refugee women who migrated to T & uuml;rkiye due to the Syrian civil war. Methods: A cross-sectional study was conducted between October 5, 2017, and January 29, 2018, with 102 lactating Syrian refugee women with infants aged 0-6 months attending the Istanbul Al Farah Child and Family Support Center. Participants were selected using convenience sampling. Inclusion criteria were being a Syrian refugee woman in the lactation period, having an infant aged 0-6 months, and volunteering to participate in the study. Women with chronic illnesses or metabolic disorders were excluded. Data were collected through face-to-face interviews with the assistance of a translator, using a structured Turkish questionnaire covering demographic information, anthropometric measurements, and 3-day dietary records. Dietary intake was analyzed with the BEBIS9 program and compared to the T & uuml;rkiye Nutrition Guide recommendations. Although the dietary data were collected in 2017-2018, the analysis was conducted using the most up-to-date national guidelines to reflect current public health priorities. Results: Participants (n = 102) had an average age of 27.9 +/- 5.7 years, BMI of 27.3 +/- 4.6 kg/m(2), and monthly income of 1267 TL. Their daily energy intake was 1593.7 +/- 556.5 kcal/day. A large proportion of participants had inadequate intake of micronutrients, with the highest insufficiency observed for pyridoxine (88.2%), followed by vitamin A (81.4%), vitamin C (76.5%), thiamine (71.5%), riboflavin (63.7%), folic acid (81.4%), vitamin B12 (72.6%), iron (62.8%), and zinc (68.6%). Women with higher BMI in early lactation consumed more fat (p < 0.05). Significant associations were found between micronutrient intake and sociodemographic factors (p < 0.05). However, due to the small sample size and use of convenience sampling, the generalizability of the findings is limited. Future studies with larger and more representative samples are needed to confirm these results. Conclusion: Syrian refugee women in the lactation period showed inadequate intake of energy and essential micronutrients, likely due to poor socioeconomic and living conditions. Interventions such as culturally sensitive nutrition education, postpartum micronutrient supplementation, and improved access to migrant-friendly healthcare services are needed. Additionally, targeted policies and sustainable public health nutrition programs-such as food voucher schemes, fortified food distribution, and maternal support groups-should be developed in collaboration with health institutions and NGOs to improve maternal and infant health outcomes in this vulnerable population.

Assessment of the Psychometric Properties of the Online Education Student Satisfaction Scale: a Methodological Study
(Springer Publishing Company, 2024) Harmancı Seren, A.K.; Alan, H.; Türkmen, E.; Gungor, S.; Baykal, Ü.
Background and Purpose: Assessing student satisfaction is essential in evaluating the quality of education. The number of valid and reliable tools that measure students’ satisfaction with online education is limited. This methodological study aimed to assess the psychometric properties of the online education student satisfaction scale. Methods: Eleven academicians from the nursing field provided expert opinions on content validity. Separate 25 students evaluated the language clarity of the draft scale. The study sample included 525 third- and fourth-year nursing students. Finally, a group of 30 nursing students different from the sample participated in the test–retest. The study created an item pool based on the recent literature. The researchers calculated the items’ content validity rates and the scale’s content validity index by taking the experts’ opinions. In addition, item–total score correlation analysis, exploratory factor analysis, discrimination analysis, stability test, and internal consistency analysis were performed. Results: An item with a low-correlation value was excluded from the scale. The correlation coefficients of the remaining items were between.536 and.811. In the second round of exploratory factor analysis, a five-factor structure emerged that explained 72.1% of the total variance. In addition, item discrimination, stability, and internal consistency test results ensured that the scale was valid and reliable. Conclusions: The online education student satisfaction scale with five subdimensions containing 28 items is a valid and reliable tool. Researchers, educators, and managers may use it to evaluate students’ satisfaction with online education. © Copyright 2024 Springer Publishing Company, LLC.

Cochleogram-Based Speech Emotion Recognition With the Cascade of Asymmetric Resonators With Fast-Acting Compression Using Time-Distributed Convolutional Long Short-Term Memory and Support Vector Machines
(Mdpi, 2025) Parlak, Cevahir
Feature extraction is a crucial stage in speech emotion recognition applications, and filter banks with their related statistical functions are widely used for this purpose. Although Mel filters and MFCCs achieve outstanding results, they do not perfectly model the structure of the human ear, as they use a simplified mechanism to simulate the functioning of human cochlear structures. The Mel filters system is not a perfect representation of human hearing, but merely an engineering shortcut to suppress the pitch and low-frequency components, which have little use in traditional speech recognition applications. However, speech emotion recognition classification is heavily related to pitch and low-frequency component features. The newly tailored CARFAC 24 model is a sophisticated system for analyzing human speech and is designed to best simulate the functionalities of the human cochlea. In this study, we use the CARFAC 24 system for speech emotion recognition and compare it with state-of-the-art systems using speaker-independent studies conducted with Time-Distributed Convolutional LSTM networks and Support Vector Machines, with the use of the ASED and the NEMO emotional speech dataset. The results demonstrate that CARFAC 24 is a valuable alternative to Mel and MFCC features in speech emotion recognition applications.
Comparative Cross-Sectional Study on Sexual Function of Couples During Pregnancy: Assisted Reproductive Techniques Versus Spontaneous Conceptions
(Womens Health & Action Research Centre, 2024) Dulger, Ozlem; Dinmez, Sinem; Torun, Sebahat D.; Osmanoglu, Usame O.
This study aims to compare the sexual functions of couples undergoing assisted reproductive techniques (ART) with those conceiving spontaneously during pregnancy. A total of 102 couples participated in this cross-sectional study, with 68 couples in the spontaneous conception group and 34 couples in the ART group. Data collection was conducted face-to-face in the antenatal clinic using separate "Descriptive Information Form" for women and men, "Female Sexual Function Index (FSFI)" for women, and "Libido Scoring System (LSS)" for men. Descriptive statistical methods, Chi-square and Fisher exact tests, t-test, and Pearson correlation test were used for data analysis. It was observed that the mean FSFI total scores of women who conceived spontaneously and through ART during pregnancy were at a good level (>= 30), while the mean LSS scores of their partners were at a moderate level (5-7). No statistically significant distinction existed among the groups. Further research is advisable by adjusting the sample selection criteria, such as gravida, duration of ART treatment, and gestational age.

Comparison of in Vitro Antifungal Activity Methods Using Extract of Chitinase-Producing aeromonas Sp. Bhc02
(Springer, 2023) Cadirci, Bilge Hilal; Yilmaz, Gulesme
Biological control to prevent fungal plant diseases offers an alternative approach to facilitate sustainable agriculture. Since the chitin in fungal cell walls is a target for biocontrol agents, chitinases are one of the important antifungal molecules. In this study, the aim was to investigate a new chitinase isolated from a fluvial soil bacterium and to show the antifungal activity of the characterized chitinase by comparing the three common methods. The bacterium with the highest chitinase activity was identified as Aeromonas sp. by 16 S rRNA sequence analysis. Following the determination of the optimum enzyme production time, the enzyme was partially purified, and the physicochemical parameters of the enzyme were investigated. In the antifungal studies, direct Aeromonas sp. BHC02 cells or partially purified chitinase were used. As a result, in the first method in which the Aeromonas sp. BHC02 cells were spread on the surface of petri dishes, no zone formation was observed around the test fungi spotted on the surface. However, zone formation was observed in the methods in which the antifungal activity was investigated using the partially purified chitinase enzyme. For example, in the second method, the enzyme was spread on the surface of PDA, and zone formation was observed only around Penicillum species among the test fungi spotted on the surface. In the third method, in which the necessary time was given for the formation of mycelium of the test fungi, it was observed that the growth of Fusarium solani, Alternaria alternata and Botrytis cinerea was inhibited by the partially purified chitinase. This study concludes that the results of the antifungal activities depend on the method used and all fungal chitins cannot be degraded with one strain's chitinase. Depending on the variety of chitin, some fungi can be more resistant.
Cross-Cultural Adaptation, Validity, and Reliability of the Turkish Version of the Cumberland Ankle Instability Tool for Athletes
(Human Kinetics Publ Inc, 2025) Yazgan, E.A.; Karagözoğlu Coşkunsu, D.; Razak Özdinçler, A.R.
CONTEXT: To cross-cultural translate the Cumberland Ankle Instability Tool (CAIT) to Turkish version (CAIT-T) and to evaluate the validity, reliability, and cutoff score of CAIT-T for Turkish athletic population. DESIGN: The English version of CAIT was translated to CAIT-T based on a guideline of cross-cultural adaptation. Fifty-two athletes with chronic ankle instability and 63 athletes without chronic ankle instability were included in the study. Construct validity was evaluated with correlations between the CAIT-T, Turkish version of Foot Ankle Ability Measure (FAAM-T), and Numeric Rating Scale. CAIT-T was completed twice by each participant at 7 to 10 days intervals to assess test-retest reliability based on the intraclass correlation coefficient, whereas Cronbach alpha evaluated internal consistency. Discriminative validity and content validity of the CAIT-T also evaluated. RESULTS: In construct validity, strong positive correlation was found between CAIT-T and Numeric Rating Scale perceived ankle instability (rho = -.771, P < .001), as well as moderate negative correlations with FAAM-T-activities of daily living and FAAM-T-sports (rho = -.448, P < .001 and rho = -0.541, P < .001, respectively). The CAIT-T demonstrated strong test-retest reliability (intraclass correlation coefficient score of .98) with a good internal consistency (Cronbach α: .85). Receiver operating characteristic curve showed a cutoff score of 26.5 (Youden index: 0.78, sensitivity: 0.57, specificity: 0.90.5). No ceiling or floor effects were observed. CONCLUSIONS: CAIT-T is a valid and reliable questionnaire for the assessment of chronic ankle instability in the Turkish athletic population.

Dodder (Cuscuta sp.) Extract Prevents Cognitive Deficits in a Rat Model of Hepatic Encephalopathy
(Kare Publ, 2024) Cevik, Ozge; Sen, Ali; Şener, Göksel; Ercan, Feriha; Doğan, Ahmet; Özbeyli, Dilek; Hatipoğlu, Bilge Nur
OBJECTIVE: In our study, the protective effect of dodder plant extract against encephalopathy induced by cholestatic liver disease model was investigated. METHODS: Spraque Dawley rats were used in the study. For the cholestatic liver disease model, the bile duct ligation (BDL) was applied. The groups were determined as control, Cuscuta sp. (CUS), BDL and BDL + CUS. Double ligation was performed in the bile duct in the BDL groups. For the applications, saline (SF) was administered to the control and BDL groups for 28 days while 250 mg/ kg of Cuscuta sp. extract was given by oral gavage to the CUS and BDL + CUS groups. At the end of the experiment, cognitive eval- uations were made by applying new object recognition and Morris water maze tests. After these tests, blood-brain barrier (BBB) measurements were made in half of the groups. In the other half of the groups, brain tissue samples were taken by decapitation and transforming growth factor-beta (TGF-β), 8-hydroxydeoxyguanosine (8-OHdG) and sodium-potassium adenosine triphospha- tase (Na+/K+-ATPase) measurements were made in the tissues. Histological examinations of the tissues were also performed. RESULTS: Cognitive performance was low, and BBB permeability was found to be increased in the group with bile duct liga- tion. In addition, TGF-β and 8-OHdG levels were increased in tissues, while Na+/K+-ATPase enzyme activity was suppressed. Treatment with Cuscuta sp. increased cognitive performance and decreased BBB permeability. Other biochemical parameters examined were significantly (p<0.05–0.001) reversed and supported by histological findings. CONCLUSION: Our findings in the study suggest that dodder plant may be beneficial for the protection of cognitive perfor- mance and brain tissue in encephalopathy caused by cholestasis. Keywords: Cuscuta sp.; cholestasis; encephalopathy; fibrosis.

(Turkish J Pediatrics, 2024) Sumengen, Aylin Akca; Ismailoglu, Abdul Veli; Ismailoglu, Pelin; Gumus, Terman; Celiker, Alpay; Namlisesli, Deniz; Cakir, Gokce Naz
Background. Understanding the severity of the disease from the parents' perspective can lead to better patient outcomes, improving both the child's health -related quality of life and the family's quality of life. The implementation of 3 -dimensional (3D) modeling technology in care is critical from a translational science perspective. Aim. The purpose of this study is to determine the effect of 3D modeling on family quality of life, surgical success, and patient outcomes in congenital heart diseases. Additionally, we aim to identify challenges and potential solutions related to this innovative technology. Methods. The study is a two -group pretest -posttest randomized controlled trial protocol. The sample size is 15 in the experimental group and 15 in the control group. The experimental group's heart models will be made from their own computed tomography (CT) images and printed using a 3D printer. The experimental group will receive surgical simulation and preoperative parent education with their 3D heart model. The control group will receive the same parent education using the standard anatomical model. Both groups will complete the Sociodemographic Information Form, the Surgical Simulation Evaluation Form - Part I -II, and the Pediatric Quality of Life Inventory (PedsQL) Family Impacts Module. The primary outcome of the research is the average PedsQL Family Impacts Module score. Secondary outcome measurement includes surgical success and patient outcomes. Separate analyses will be conducted for each outcome and compared between the intervention and control groups. Conclusions. Anomalies that can be clearly understood by parents according to the actual size and dimensions of the child's heart will affect the preoperative preparation of the surgical procedure and the recovery rate in the postoperative period.

The Effect of myrtus Communis L. Extract on Nephrolithiasis Model in Rats
(Kare Publ, 2024) Ertas, Busra; Dorucu, Dogancan; Gulerturk, Oznur; Sen, Ali; Cevik, Ozge; Cetinel, Sule; Sener, Goksel
OBJECTIVE: Nephrolithiasis is a common urological disease that can lead to renal failure. Oxidative stress has been shown to be a contributing factor for nephrolithiasis and many agents have been studied to prevent and treat oxidative stress-related nephrolithiasis and renal damage. Myrtus communis (MC) extract has been shown to be an important antioxidant in different animal models. In this study, MC extract was administered preventively or therapeutically to rats with kidney stones, and its effectiveness was investigated. METHODS: Wistar albino rats were divided into four groups (n=8); control (C), ethylene glycol (EG), EG+preventive MC, and EG+curative MC groups. The nephrolithiasis model was created by adding 0.75% EG to drinking water for 8 weeks. Ultimately, 24-hour urine was collected to measure calcium, citrate, and creatinine levels. After decapitation, kidney tissues were harvested for histological analyses, measurement of osteopontin and 8-hydroxydeoxyguanosine (8-OHdG) levels, and N-acetyl-beta-glucosaminidase (NAG), myeloperoxidase (MPO) and caspase-3 activities. RESULTS: In 24-hour urine samples, calcium, citrate and creatinine levels were decreased in the EG group, while oxalate levels were increased and in treatment groups these parameters returned to control levels. MPO, 8-OHdG, caspase-3 and NAG activity were significantly increased in tissue and these changes were reversed in both MC groups. Histological findings also supported the biochemical parameters. CONCLUSION: MC can reduce oxidative stress and histopathological changes in kidney tissues in rat nephrolithiasis model when used as either a preventive or therapeutic agent. If supported with further clinical trials, MC might have clinical implications in preventing oxidative renal cell injury and ultimately kidney stone formation.
The Effect of Simulation-Based Electroconvulsive Therapy Education on Perception and Knowledge of Nursing Students: a Semiexperimental Study
(Lippincott Williams and Wilkins, 2025) Dikeç, G.; Şan, E.Ö.
Objectives Despite the recognized benefits and safety of electroconvulsive therapy (ECT) for treating mental disorders, negative perceptions persist among both the public and mental health professionals. This stigma is often rooted in historical practices and media portrayals, despite modern advancements in the technique. This study aimed to assess the impact of simulation-based ECT education on nursing students' perceptions and knowledge regarding ECT before and after the procedure. Methods This study was planned to use a single-group pretest and posttest quasi-experimental design with a 3-month follow-up. Simulation-based ECT education involved 1 hour of theoretical instruction followed by hands-on learning using a high-fidelity mannequin. Final-year nursing students enrolled in a psychiatric and mental health nursing course were examined on their knowledge and perceptions of ECT before, immediately after, and 3 months following the intervention. Results Students reported statistically significant improvements in their perception and knowledge levels after participating in the simulation-based ECT education. The results were similar at the 3-month follow-up. Conclusions Simulation-based ECT education can be effectively integrated into both undergraduate and graduate nursing curricula to foster positive perceptions and enhance knowledge about ECT.

The Effect of Sportive Latin American Ballroom Dance on Foot and Ankle Posture
(Amer Podiatric Med Assoc, 2025) Kayiskiran, Onurcan; Coskunsu, Dilber Karagozoglu; Isiklar, Cagdas
Background: Correct use of the feet, step techniques, and positions constitute significant factors in the success of a dancer. Moreover, the type of dance has crucial effects on the posture of the foot and ankle. Therefore, the primary aim of our study was to determine whether there was a relationship between dancesport, dance experience (years), shoe-wearing time (hours), and shoe heel height (centimeters) in dance athletes performing Sportive Latin American Ballroom (SLAB) dance. Second, we aimed to compare the foot posture of SLAB dancers and nondancers with similar demographic characteristics. Methods: Twenty-six professional SLAB dancers and 26 nondancers who had similar demographic characteristics and did not use high-heeled shoes volunteered to take part in this study. Foot posture (using the Foot Posture Index [FPI]), foot pronation (using the navicular drop test [NDT]), tibiocalcaneal angle, hallux valgus angle (HVA) (using a goniometer), and ankle dorsiflexion range of motion (ROM) (using the weightbearing lunge test) were evaluated. Results: There was a positive moderate correlation between FPI score and shoe-wearing time on the dominant (P = .041; r = 0.40) and nondominant (P = .026; r = 0.43) sides. A positive very good correlation was found between shoe heel height and HVA (P < .001; r = 0.75). A negative good correlation was observed between years of dancing and nondominant ankle dorsiflexion ROM (P = .027; r =-0.43). When dancers and nondancers were compared, a statistically significant difference was found between FPI and NDT scores (P < .001). The FPI and NDT scores, tibiocalcaneal angle, HVA, and ankle dorsiflexion ROM were significantly greater in the dancer group compared with the nondancer group (P < .001) in all measurements of the dominant and nondominant sides. Conclusions: Revealing the relationship between dance experience and shoe-wearing time and the difference between the foot posture and deformities of athletes who perform SLAB dance and those of nondancers constitutes a pivotal endeavor that will increase awareness and knowledge among dancers and clinicians.

Effectiveness of Non-Invasive Vagal Nerve Stimulation in Parkinson's Disease: a Comprehensive Systematic Review And Meta-analysis
(Elsevier Sci Ltd, 2025) Abouelmagd, Moaz Elsayed; Yousef, Obai; Ibrahim, Ismail A.; Elshahat, Ahmed
Background: Parkinson's disease (PD) is a debilitating neurodegenerative disorder characterized by movement impairments. Vagus nerve stimulation (VNS) is a non-invasive brain stimulation technique that has shown promise in treating various neurological conditions, including PD. This systematic review aimed to evaluate the existing evidence on the efficacy of nVNS in managing PD symptoms. Methods: A comprehensive literature search was conducted to identify relevant studies published up to July 2024. The included studies investigated the effect of nVNS on various PD motor symptoms. The quality of studies was assessed using the Cochrane Risk of Bias 2 (ROB-2) and NIH tool for RCTs, single-arm studies, and case series studies respectively. Statistical analysis was conducted using Review Manager version 5.4.1 with outcomes expressed as Mean differences (MD) with 95% confidence intervals (CI). Results: The systematic review included eight randomized controlled trials (RCTs), one single-arm study, and one case series, encompassing a total of 217 patients with PD. The review revealed that nVNS in increasing Freezing of Gait (FOG) in PD (p = 0.04). However, no significant differences were found in UPDRS-III (p = 0.19 and p = 0.89 for on and off-medication conditions, respectively), UPDRS-II (p = 0.9), UPDRS-I (p = 0.46), Time Up and Go (p = 0.61), stand time (p = 0.87), walking speed (p = 0.22), or step length measured in meters (p = 0.8). Interestingly, a significant improvement was observed in step length measured in centimetres (p = 0.0005). No study reported serious adverse effects associated with nVNS treatment. Conclusion: Our finding suggests a potential benefit of nVNS in reducing FOG in PD, but did not demonstrate a significant improvement in other motor symptoms. Larger, longer follow-up studies are needed to confirm the effect nVNS on PD management. PROSPERO number: CRD42024574822.

Effects of Balance and Strength Training for Ankle Proprioception in People With Chronic Ankle Instability: a Randomized Controlled Study
(Amer Podiatric Med Assoc, 2024) Yekdaneh, Asena; Mutlu, Cigdem Yazici
Background: After an ankle sprain, the ligament and joint capsule are damaged, and as a result, proprioceptive sense is damaged, causing a feeling of giving away in the ankle and resulting in recurrent sprains. Given the relevant studies, it has been seen that people with chronic ankle instability (CAI) commonly have deficits in joint position sense and reinjury risks. Joint position sense plays an important role in ankle control, thereby reducing the risk of injury. Therefore, this study aims to compare the effects of balance and strength training on ankle proprioception in people with CAI. Methods: This single-blind randomized controlled study included 29 volunteer participants (21 women and eight men) aged 18 to 30 years. Participants with a Cumberland ankle instability scale score less than or equal to 24 were randomly divided into two treatment groups: strength training (n = 14) and balance training (n = 15). Y balance test, joint position, and vibration sense were evaluated at the beginning and end of the treatment. "Hop to stabilization" exercises were applied to the balance group and resistive bands exercises to the strength group, which were performed for 6 weeks, 35 minutes per day, two times per week. Results: There was no significant difference between the two groups in the anterior, posterolateral, and posteromedial directions of the Y balance test (P = .89, P = .50, and P = .34, respectively), but the strength training group showed significant improvement in ankle proprioception (140 degrees) and vibration sense (fifth finger) (P < .001), and the post hoc Cohen's d effect size values were medium (.52) and small (.25), respectively. Conclusions: The findings of this study show that strengthening and balance exercises have similar effects on dynamic balance, but strengthening exercises are more effective in improving joint position and vibration sense. Given the positive effects of both exercise programs, it is recommended to implement the two interventions separately or together for CAI rehabilitation.

Effects of Computer-Based Balance Exercises on Balance, Pain, Clinical Presentation and Nerve Function in Patients With Diabetic Peripheral Neuropathy: a Randomized Controlled Study
(International Society of Musculoskeletal and Neuronal Interactions, 2024) Reyhanıoglu, D.A.; Yıldırım, G.; Sengun, I.Ş.; Kara, B.
Objective:To evaluate the use of a computer-based biodex balance exercise system (BBS) on balance, neuropathic pain, clinical presentation and nerve function in patients with diabetic peripheral neuropathy (DPN). Methods: A total of 32 participants with DPN were randomly assigned in a 1:1 ratio to an intervention group (IG) or control group (CG). The IG performed exercises using the BBS twice weekly for 8 weeks, while CG were informed regarding diabetes self-management. At baseline and after study completion, participants underwent balance (postural stability and fall risk) and neuropathic pain assessment (DN4 questionnaire) and were screened using the Michigan Neuropathy Screening Instrument and nerve conduction test. Results: Among the baseline participants, 14 in the IG and 13 in the CG completed the study. Balance training improved postural stability (overall, p<0.001), fall risk (p<0.001), neuropathic pain (p=0.01) and symptoms (p<0.001), and clinical presentation (p=0.02), but not nerve function, within the IG. At follow-up, IG displayed significantly improved stability (p<0.001) and fall risk (p=0.02) and decreased neuropathic symptoms (p=0.01) compared to the CG. Conclusion: Computer-based balance exercises improve balance, pain, and clinical presentation of DPN, but not nerve function, in patients with DPN.

Effects of Manual Versus Instrumental Spinal Manipulation on Blood Flow of the Vertebral and Internal Carotid Arteries in Participants With Chronic Nonspecific Neck Pain: a Single-Blind, Randomized Study
(Elsevier inc, 2023) Kocabey, Burcu; Coskunsu, Dilber Karagozoglu; Guven, Koray; Agaoglu, Mustafa H.; Yuce, Selvi
Objective: The aim of this study was to compare the hemodynamic effects of manual spinal manipulation (MSM) and instrumental spinal manipulation (ISM) on the vertebral artery (VA) and internal carotid artery (ICA) in participants with chronic nonspecific neck pain (NNP). Methods: Thirty volunteers aged 20 to 40 years old with NNP over 3 months duration were included. Participants were randomly divided into the following 2 groups: (1) MSM group (n = 15) and (2) ISM group (n = 15). Ipsilateral (intervention side) and contralateral (opposite side of intervention) VAs and ICAs were evaluated using spectral color Doppler ultrasound before and immediately after manipulation. Measurements were recorded by visualizing the ICA carotid sinus (C4 level) and the VA at the V3 segment (C1-C2 level). The blood flow parameters of peak systolic velocity (PSV), end-diastolic velocity, resistive index, and volume flow (only for VA) were evaluated. The spinal segment, in which biomechanical aberrant movement was detected by palpation in the upper cervical spine, was manually manipulated in the MSM group. The same methodology was performed for the ISM group using an Activator V instrument (Activator Methods). Results: Intragroup analysis exhibited no statistically significant difference between the MSM and ISM groups in terms of PSV, end-diastolic velocity, resistive index of ipsilateral and contralateral ICA and VA, in addition to volume flow of both VAs preintervention and postintervention (P > .05). Within the intergroup analysis, there was a significant difference in ipsilateral ICA PSV (P = .031) (preintervention vs postintervention difference was -7.9 & PLUSMN; 17.2 cm/s [95% confidence interval, -17.4 to 1.6] in the ISM group and 8.7 & PLUSMN; 22.5 cm/s [95% confidence interval, -3.6 to 21.2]) in the MSM group (P < .05). Other parameters did not show any significant difference (P > .05). Conclusion: Manual and instrumental spinal manipulations applied to the upper cervical spine in participants with chronic NNP did not appear to alter blood flow parameters of the VAs and ICAs.

(Elsevier Science inc, 2024) Anilir, Ender; Topcu, Feyza Sonmez; Sahin, Emrah; Oral, Alihan; Civan, Hasret Ayyildiz; Poyrazoglu, Kursat Orhan; Unal, Bulent
Objective. It was aimed to examine the overall role of cold ischemia time and anhepatic phase durations in terms of peroperative blood transfusion needs, hospital stay conditions and postoperative charges, and survival in recipients. Material and Methods. One hundred forty-eight adult living donor liver transplant recipients (18 years and older) were included in the study. Whether the anhepatic phase and cold ischemia duration have an effect on the rates of surgery time, blood product transfusion, total hospital and intensive care unit stay, postoperative biliary complications, hepatic vein thrombosis, portal vein thrombosis, early postoperative bleeding, sepsis, and primary graft dysfunction. Was analyzed statistically. In addition, the effect of the anhepatic phase and cold ischemia time on graft survival was statistically examined by creating an average of the patient follow-up period. Results. It was observed that the operation time increased statistically as the cold ischemia time increased (P P = .000). No statistically significant fi cant relationship was found between other fi nd- ings and cold ischemia time and anhepatic phase. Conclusion. Prolonged surgery time due to increased cold ischemia time may be an important fi nding in terms of peroperative and postoperative results of the graft.
Emergency Department Nurses' Knowledge and Practices Related To Extravasation Injuries of Non-Cytotoxic Medications
(Turkish Assoc Trauma Emergency Surgery, 2025) Kugu, Emre; Akyuz, Nuray
BACKGROUND: Extravasation of non-cytotoxic medications can lead to serious complications such as pain, tissue necrosis, limb loss, and even death. This descriptive cross-sectional study aims to assess the knowledge levels of emergency department (ED) nurses regarding extravasation incidents involving non-cytotoxic medications and to highlight the importance of effective management and prevention. METHODS: The study was conducted in the EDs of three hospitals in Istanbul, T & uuml;rkiye, between November 19, 2020 and December 31, 2020. A total of 100 ED nurses participated in the study. Inclusion criteria required nurses to be working full-time in the EDs during the study period and to provide written and verbal consent. The study utilized a survey to assess sociodemographic characteristics, knowledge of non-cytotoxic medications (e.g., epinephrine), symptoms of extravasation, prevention strategies, and intervention practices. RESULTS: The mean age of the nurses was 29.43 years, with 57% female and 73% holding a bachelor's degree. Among participants, 52% had 0-3 years of ED experience. Ninety-one percent reported not receiving education on extravasation after graduation, and 82% indicated no extravasation protocol was in place at their workplace. Knowledge about non-cytotoxic medications causing extravasation significantly increased with ED experience (p=0.035). Nurses in units with an extravasation protocol had significantly higher knowledge levels (p=0.007). Female nurses demonstrated better knowledge of extravasation symptoms than male nurses (p=0.012). Nurses with a bachelor's or higher degree had significantly better knowledge than others (p=0.015). The knowledge rate for the extravasation care protocol was 64%, with the most recognized protocol item being "immediately stop the infusion" (97%) and the least recognized being "aspirate the medication not to exceed 3-5 mL" (33%). Strong correlations were found between non-pharmacological factors and knowledge of non-cytotoxic medications (r=0.601; p<0.001), as well as between knowledge of extravasation care protocols and non-pharmacological factors (p<0.001). CONCLUSION: The study highlights the need for targeted education and the establishment of institutional protocols for managing and preventing extravasation in EDs. Nurses' knowledge significantly impacts their adherence to prevention and care protocols. To ensure patient safety, it is important to provide ongoing education and implement evidence-based intervention protocols for the management of extravasation in ED settings.

Ethanolic Extract of Cotinus Coggygria Leaves Attenuates Crystalluria and Kidney Damage in Ethylene Glycol-Induced Urolithiasis in Rats
(Kare Publishing, 2023) Gumru, S.; Ozgur, G.; Ertas, B.; Sen, A.; Eker, P.; Sener, T.E.; Sener, G.
OBJECTIVE: Nephrolithiasis is a common cause of kidney insufficiency. Nephrolithiasis is proven to be the result of various biochemical and inflammatory processes that result in crystal formation and subsequent aggregation. Cotinus coggygria L. (CCog) is a plant extract which has been used as a Turkish remedy for kidney stones. With this study, we planned to evaluate the effects of CCog extract in ethylene glycol (EG)-induced nephrolithiasis model in rats. METHODS: The study group comprised 32 Wistar albino rats which were divided into Control (C), EG, CCog Prophylaxis (CC+EG+CC), and CCog Treatment (EG+CC) groups. Stone formation was induced by adding EG (0.75%) into rat’s drinking water. Normal drinking water was given to Control group for 8 weeks. Throughout the study period of 8 weeks, EG group was given only EG (0.75%) and CC+EG+CC group was given both EG and CCog. In EG+CC group, EG (0.75%) was given for 8 weeks whereas CCog was given for the past 4 weeks. After the 8th week, 24-h urine samples were collected. Rats were then sacrificed and kidney tissue samples were harvested. RESULTS: Metabolites (calcium, citrate) and creatinine in 24 h urine samples were decreased in CC+EG+CC and EG+CC groups. While hyperoxaluria was observed in the EG group, oxalate levels were similar to control levels in the P-CCog and C-CCog groups. The N-acetyl-β-glucosaminidase and myeloperoxidase activities were both increased in EG group and these parameters were significantly decreased on CCog treatment. CONCLUSION: We can conclude that C. coggygria extract can have beneficial effect on lowering concentration of stone-forming metabolites in urine and consequently protect renal tissues from damage due to nephrolithiasis. C. coggygria extract can be considered as a potential prophylactic and therapeutic option in high-risk stone formers. Furthermore, our data confirm ethnobotanical use of CC against nephrolithiasis. © 2023 by Istanbul Provincial Directorate of Health.
